Comparing LED Lighting Systems in the Detection and Color Recognition of Roadway Objects
… LED luminaires and their abilities to provide detection distance and color recognition distance of potential roadway hazard. Detection distance is regarded as a metric of visibility. Color recognition distance is a metric for comparing the impact of the (Correlated Color Temperature) CCT of …

Identification of Weather Conditions Related to Roadside LiDAR Data
… transit buses, and pedestrians. Roadside Light Detection and Ranging (LiDAR) sensors can be deployed to collect such high-resolution traffic data sets. However, LiDAR sensing could be negatively affected in the context of rain, snow, and wind conditions as the collected 3D point clouds of …

Nighttime Driving Evaluation of Disability and Discomfort Glare from Various Headlamps under Low and High Light Adaptation Levels
… that there would be significant differences in detection distance and discomfort glare rating across the different glare headlamp and adaptation level combinations. It was also hypothesized that age would have a significant effect on detection distance, and the subjective ratings. The results of …

The effect of prey availability on metabolism and activity in the tarantula <i>phormictopus cancerides</i> (araneae: theraphosidae)
… locomotory activity, and (4) the predator’s prey detection distance. RMRs increased for the well-fed group but remained consistent for individuals, fed only once a month. Time to prey capture decreased for food-limited individuals, and the proportion of individuals that ate in the 30-day group was …

Variation of echolocation pulse source levels and detection distances for bat assemblages across an environmental gradient: “a test of the acoustic adaptation hypothesis”
… Source levels used by bats impacts on the distance at which bats perceive their targets like prey in their habitats. Habitat and prevailing climatic conditions present different challenges for echolocation systems, and so the quality and content of information derived from echolocation …

Azimuthal Localization and Detection of Vehicular Backup Alarms Under Electronic and Non-Electronic Hearing Protection Devices in Noisy and Quiet Environments
… ability to detect backup alarm signals in the distance dimension, is lacking in the acoustics and safety literature. Accordingly, two research experiments were conducted for this dissertation. In the first experiment, the effect of seven hearing protectors, two background pink noise levels (60 …

The Computational Neuroethology of Weakly Electric Fish: Body Modeling, Motion Analysis, and Sensory Signal Estimation
… to intercept prey. In addition, nonvisual detection distance was dependent on water conductivity, implying that detection is dominated by the electrosense and providing the first evidence for the involvement of this sense in prey capture behavior of gymnotids. An analysis of the …

Tactical Escape Behavior and Performance of a Small Sceloporine Lizard in Two High Risk Habitats
… Longleaf pine lizards had greater flight and detection distance than in sand pine scrub. Males showed greater risk aversion and were easier to detect than females in both habitats, indicating that they may be more sensitive to predation when conspicuously occupying open areas. Overall this …

Methods of optimization for KCE-based aptamer selection
… into the capillary and carried towards the detection point by applying a low pressure. A dual on-column detector is mimicked by repeating the experiment using the same capillary but a shortened distance to the detection window. The temporal propagation pattern of the protein, at each …

Assessment of the Effectiveness of Emergency Lighting, Retroreflective Markings, and Paint Color on Policing and Law Enforcement Safety
… high output blue lighting system increase the distance at which drivers moved over significantly. In general, at least 95% of traffic attempted to merge away from an actively lighted police vehicle, when possible. In terms of the speed change, drivers began reducing their speed by approximately …

Multi-defect localization and evaluation techniques for distribution cables based on time-domain reflectometry
… of efficient and reliable methods for defect detection and localization in power cables is of great practical significance. Time Domain Reflectometry (TDR) is widely used for detecting and localizing cable defects. By injecting a pulse signal into the cable and analyzing the reflected signal, …

Habitat correlates of pulse parameters in the highly specialised acoustic system of Chiroptera
… attenuation making them more suited to long distance prey detection. Previous research has therefore focused on the methods by which bats vary the frequency of their pulses to achieve optimal propagation distances. However, the source levels of these signal emissions are also under control of …
